An electrocardiograph that integrally has the same number of lead wires that can hold the electrocardiogram electrode main body at the signal collection site, and the same number of signal output terminals that are electrically connected to the other ends of each of the lead wires. and the same number of connectable connectors, and is configured to transmit an electrocardiogram signal to an electrocardiograph.

Here, the signal output terminal section is usually formed of a plurality of independent bottle-shaped metal rods corresponding to each electrocardiogram electrode main body section, and the same number of connectors are provided with the signal output terminal sections in a protruding state. There is.

Also, a connector is known in which the entire connector is cylindrical, and the signal output terminal portion can be engaged with a corresponding terminal portion of an electrocardiograph.

[Problems to be Solved by the Invention] However, as described above, conventional connectors are formed in the same number corresponding to each electrocardiogram electrode main body, and since there are a plurality of connectors, it is difficult to make a mistake when connecting to an electrocardiograph. There was a risk that the terminals would be connected to different signal output terminals.

Furthermore, connecting a plurality of connectors to the electrocardiograph one by one requires labor and time, which poses a problem of a lack of speed, and there is a risk of poor contact at the connecting portions.

In addition, since the connector has a structure in which a plurality of bottle-shaped metal rods are used as signal output terminals, manufacturing costs are high, and there are problems in that it is difficult to make the entire electrocardiogram electrode a disposable type. Ta.

The present invention has been made in view of these problems, and when connecting a biological electrode to an electrocardiograph, there is no risk of accidental connection, and the connection operation can be easily performed in one go. The purpose of the present invention is to provide a disposable biomedical electrode that can be used at a low manufacturing cost and has improved stability during use.

[Function] When using the biological electrode according to the present invention, first,
The biological electrode main body is attached to a predetermined position on the living body.

Next, the connector to which the other end of the lead part is connected is connected to the input part of a measuring instrument such as an electrocardiograph.

At this time, since the connector has a flat plate shape, the proper connection position of the signal output terminal part of the connector can be recognized, and when connecting the connector to a measuring device such as an electrocardiograph, it is possible to connect it incorrectly. There is no fear.

Furthermore, the connector has a plurality of signal output terminals to which the other end of each lead is electrically connected, and is composed of a single connector, so it can be connected without error in - number of connection operations. I can do it.

Further, during use, there is no risk of poor contact at the connection portion, so it can be used stably.
